What is the estimated probability that at least two of the puppies will be female?
O A. 5/10 = 50%
O B . 8/10 = 80%
O C. 3/10 = 30%
O'D. 7/10 = 70%

B. 8/10 = 80%

Step-by-step explanation:

number of sample space ( that is the total of the results)

n(s) = 10

the question says at least two of the puppies will be female.

let heads,h, = female puppies

then, we check the results;

number of at least two h [n( at least two h)] = , tthh, hhtt, thth, htth, hhht, hhtt, hthh.

n( at least two h) = 8

probability of at least two of the puppies will be female ( pr of at least h) = n( at least h )

n(s)

=8 = 80%

10

square root

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
